I purchased one of these to bolster the deep bass for a pair of Klipschorns. It can keep up with the mains. My Emotiva XSP-1Gen2 Preamp has analog, discrete-element low-pass crossovers with adjustable crossover points from 50hz to 250hz. The Klipsch has a similar control built in, of course, which when fully rotated to LFE eliminates its filtering. After trying it both ways, I felt the sound was slightly better bypassing the Klipsch crossover and using the Emotiva's. However, it was so close that it was a tough call.
I have owned a lot of audio gear over many years, and this is the best-sounding system I've had in my home. Bass is clean, articulate and sounds effortless. I was using another brand of sub prior to this 15" behemoth's arrival, and I now realize it was mush. I knew it was rather soft, but I didn't really understand the full scope of its shortcomings until connecting this bad boy. It made my corner-horns sound even better. I see where a La Scala owner claimed the bass was not as clean as his mains. I understand what he means, but point out that neither his La Scalas nor my Khorns reach as deep into the bass as this sub, which is the point of having it - it is very clean all the way down and quite remarkable for the price. Perhaps not quite as tight as our large Klipsch Heritage models, but not far from it, either. Which is quite a feat.
If I had the space, I might add a second R-115SW, but I don't feel a bit short-changed with a single. It's combination of sound quality, bass depth, and price make it a fantastic choice for the big Klipsch main speakers. It is large, but actually compact, considering its output and the kind of company it keeps.

Subwoofer Weight = 5.76 cats; Subwoofer Performance = The Cat's Meow!
The only time I have ever encountered bass this responsive and tight is in the movie theatre where I worked, projecting movies and tweaking sound set-ups for the better part of a decade. As far as I am concerned, this is the entry-level subwoofer for creating your very own movie theatre-like soundscape. It has smartbomb-like precision in its bass delivery for film, and its musical bass reproduction is beautiful (which is not an adjective usually ascribed to a sub).The only issue you may run into is the size factor. You can see how large this puppy is compared to the cat (his name is Buster) sitting on it in the image provided. Buster is around 13 lbs. for reference, which means this puppy is quite large. But it's worth its weight in performance gold from a home theatre standpoint as it shines in my 9 ft ceilings with a fully open floor layout. It only took an evening of movie-watching and music-listening fun for my wife to warm up to its excellence -- not an easy feat! I highly recommend this sub, and I hope you enjoy it as much as I have during a broad scope of film viewings as well as a variety of musical listening experiences (including modern and classic pop, orchestral film scores, classic rock, a cappella, and hip hop).
